Definitions

  • the invention relates to a spring hinge for spectacles having two hinge parts connected in an articulated manner to one another by a spring axis, of which one hinge part is mounted in a hinge housing so it is displaceable against a retracting spring force and the other hinge part, which is supported on the hinge housing via a centering, forms at least one stop face which works together with the front side of the hinge housing in a stretched position of the hinge parts.
  • Spring hinges for spectacles allow overstretching of the stretch length of the hinge joint predefined by a stop without having to fear damage to the hinge joint and at least secure the stretched position by an elastic stop.
  • spring hinges for spectacles are known in various embodiments, all spring hinges share the feature that one of the two hinge parts, which are connected to one another in an articulated manner by a hinge axis, is mounted in a hinge housing so it is displaceable and is impinged by at least one spring in the direction of retraction into the hinge housing.
  • the other hinge part is supported at least in a stretched position of the hinge part via a stop face on the front side of the hinge housing with an elastic pretension, so that the stretched position thus caused is predefined.
  • the hinge part mounted in the hinge housing may be displaced against the force of the spring and release the pivot movement of the earpiece beyond the stop-limited stretched position.
  • a V-shaped recess having an opening angle of 90° in the front side of the hinge housing is known (EP 0 736 790 A1), in which a right-angled projection of the hinge part connected to the spectacle frame may engage in two rotational positions angularly offset by 90°.
  • the invention is thus based on the object of designing a spring hinge of the type described at the beginning in such a manner that guiding of the spectacle earpiece largely without play may be ensured, without endangering the easy displaceability of the hinge part mounted in the hinge housing.
  • the centering provided between the stop face of one hinge part and the front side of the hinge housing comprises at least one centering groove running around the circumference of the hinge axis and a centering projection, which engages in this centering groove at least in the stretched position of the hinge parts.
  • the two hinge parts are fixed in relation to the hinge housing largely free of play, so that a corresponding guide for the spectacle earpiece which is free of play results. Even with a centering of the earpiece which is only provided in a limited pivot range, secure engagement of the centering projection in a centering groove is ensured.
  • the retracting spring load of the hinge part mounted so it is displaceable in the hinge housing causes elastic pressing of the stop face of the hinge part not mounted in the hinge housing against the housing front side with the effect that the centering projection engages without play in the centering groove, which preferably has a wedge-shaped cross-section, and independently of whether the centering projection belongs to the housing front side or the stop face.
  • centering projection may fundamentally also be provided on the stop face of one hinge part, more advantageous design conditions result if the centering projection is assigned to the front side of the hinge housing and the centering groove is assigned to the stop face of this hinge part, because the stop face of the hinge part may be provided more easily with a centering groove than with a centering projection, in particular if the centering groove is to extend over the entire pivot angle of the associated hinge part to ensure continuous centering engagement.
  • a centering projection may be provided on the front side of the hinge housing on both sides of a central hinge lobe of the hinge part displaceably guided in the hinge housing, the central hinge lobe forming a centering groove for receiving the centering projections between accommodating hinge lobes of the other hinge part in the area of the stop faces, so that an earpiece centering occurs on both sides of the central hinge lobe of the spring hinge.
  • FIG. 1 shows a spring hinge of a pair of spectacles according to the invention in a simplified side view
  • FIG. 2 shows this spring hinge in a top view
  • FIG. 3 shows a section along line III-III of FIG. 1 ,
  • FIG. 4 shows an illustration of a design variant of a spring hinge according to the invention corresponding to FIG. 1 ,
  • FIG. 5 shows the spring hinge from FIG. 4 in a top view
  • FIG. 6 shows the spring hinge from FIGS. 4 and 5 in detail in the area of the centering in a section along line VI-VI of FIG. 4 in an enlarged scale.
  • the spring hinge according to FIGS. 1 through 3 typically has a hinge housing 1 connectable to a spectacle earpiece, in which a sliding part 2 of a hinge part 3 forming a central hinge lobe 4 is displaceably guided. This sliding part 2 is impinged with the aid of a spring in the direction of an insertion of the hinge part 4 into the hinge housing 1 .
  • the hinge part 5 connectable to a spectacle cheek has two hinge lobes 6 enclosing the central hinge lobe 3 on both sides.
  • the hinge axis, which penetrates the hinge lobes 3 and 6 in the form of a screw, is identified by 7 .
  • the hinge part 5 assigned to the spectacle cheek forms two stop faces 8 and 9 , which work together with the front side of the hinge housing 1 and on one hand fixes the stretched position of the hinge parts 4 , 5 and thus the stretched position of the earpiece shown in the drawing and on the other hand fixes an earpiece position folded in against the spectacle frame, because the stop faces 8 , 9 are pressed against the front side of the hinge housing 1 by the spring impinging the sliding part 2 in the particular pivot position of the hinge joint.
  • the elastic pressing of the stop faces 8 and 9 against the housing front side may advantageously be used for guiding the earpiece without play.
  • a centering is provided between the front side of the hinge housing 1 and the stop faces 8 , 9 , which is formed on one hand by at least one centering groove 10 , which is wedge-shaped in cross-section, and is formed on the other hand by a centering projection 11 engaging in the centering groove 10 .
  • each of the two hinge lobes 6 of the hinge part 5 has a centering groove 10 extending over both stop faces 8 , 9 , while corresponding centering projections 11 in the form of hinge strips are provided on the front side of the hinge housing 1 , which run like the centering grooves 10 around the circumference in relation to the hinge axis 7 , so that the hinge part 5 is fixed without play in relation to the hinge housing 1 in the direction of the hinge axis 7 , because the centering projections 11 are pressed into the centering grooves 10 as a result of the retracting spring load of the hinge part 4 .
  • the spring hinge according to the embodiment from FIGS. 4 through 6 differs from that from FIGS. 1 through 3 essentially only in the type of the centering, because the centering is only active between the stop face 8 of the hinge part 5 for the stretched position of the hinge joint and the front face of the hinge housing 1 .
  • the centering grooves 10 are provided in the area of the stop face 8 , which only extends over a partial area of the front side of the hinge housing 1 . This means that the earpiece connected to the hinge housing 1 is held without play only in the stretched position, i.e., in its usage position, which is sufficient for the usage of the spectacles, however.
